Abstract

Pada penelitian ini telah dilakukan sintesis antara serbuk partikel nano TiO2 dan serbuk partikel nano ZnO menjadi pasta yang akan diaplikasikan sebagai elektroda pada dye-sensitized solar cell (DSSC). Elektroda pada DSSC ini bekerja berdasarkan adsorbsi foton oleh pewarna, elektron yang tereksitasi ditransfer ke TiO2/ZnO yang mempunyai perbandingan berbeda. Dimensi material partikel nano TiO2/ZnO sebagai elektroda sangat penting untuk menghasilkan efisiensi yang lebih tinggi pada DSSC. Sifat ini sangat dipengaruh oleh metoda pabrikasi elektroda TiO2/ZnO dan parameternya. Pada penelitian ini digunakan metoda doctor blade untuk pabrikasi DSSC dan larutan dyes (Z907) sebagai zat pewarna. Tujuan penelitian ini adalah untuk mengetahui pengaruh pencampuran serbuk TiO2 dan serbuk ZnO sebagai elektroda. Teknik pembuatan pasta TiO2/ZnO sebagai elektroda sangat penting untuk menghasilkan efisiensi tinggi pada DSSC. Teknik ini sangat terkait dengan material TiO2/ZnO, metoda pabrikasi, dan parameter pengukurannya. Dalam penelitian ini dibahas hasil karakterisasi XRD pada kedua serbuk TiO2 dan ZnO, hasil SEM pada pencampuran kedua material, hasil pengujian IPCE serta hasil pengukuran effisiensi pada pengujian I - V.

Abstract

Dye-sensitized solar cells (DSSC) are widely developed due to their attractive appearance and simple fabrication processes. One of the challenges that arise in the DSSC fabrication involves high material cost associated with the cost of conductive substrate. DSSC with monolithic configuration was then developed on the basis of this motivation. In this contribution, titanium dioxide-based monolithic type DSSCs were fabricated on a single fluorine-doped transparent oxide coated glass using porous ZrO2 as spacer. Herein, the catalytic material for the counter-electrode was varied using carbon composite and platinum in order to analyze their effect on the solar cell efficiency. Four-point probe measurement revealed that the carbon composite exhibited slightly higher conductivity with a sheet resistance of 9.8 Ω/sq and 10.9 Ω/sq for carbon and platinum, respectively. Likewise, the photoconversion efficiency of the monolithic cells with carbon counter-electrode almost doubled the efficiency of the cells with platinum counter-electrode. Our results demonstrate that carbon could outperform the performance of platinum as catalytic material in monolithic DSSC.

Abstract

Dye-sensitized solar cells (DSSC) has been well known as a highly competitive photovoltaic technology owing to its interesting characteristics, such as, low-cost, simple, and convenient to modify both chemically and physically. One way to reduce the production cost of DSSCs is to conduct a structural modification in the form of a monolithic structure by using a single conductive substrate to accommodate both photoelectrode and counter electrode. However, the photovoltaic performance of monolithic DSSCs is typically still lacking compared to its conventional DSSCs counterparts that uses sandwich structure. One of the crucial factors that determine the photovoltaic performance of a monolithic DSSC is its electrolyte. In this work, the performance of monolithic DSSCs were studied through modifications of the electrolyte component. Two types of commercial liquid electrolytes that have different chemical properties were used and combined into various compositions, and the resulting DSSCs performances were compared. The stability of the monolithic cells was also monitored by measuring the cells repeatedly under the same condition. The result showed that during the first measurement the highest performance with a power conversion efficiency of 1.69% was achieved by the cell with a higher viscosity electrolyte. Meanwhile, the most stable performance is shown by the cell containing lower viscosity electrolyte, which achieved an efficiency of 0.66% that measured on day 35.
